fuel injectors?

[redbird00]

what size injectors would be a good upgrade, and what kinda gains would i see? or would it even be beneficial?

Bigger injectors will give you the capability for more fuel. You need more air to go with that fuel. (unless you are just wanting to run rich)

So unless you are doing a power adder (blower, nitrous, turbo) or a big cam, the additional fuel capability won't help you.

If anything, bigger injectors will cause you to lose power at wot, unless you reprogram for them. Because you will be running richer than the ideal a/f ratio for peak power.

im not certain i just feel that my car is running lean, because of the mods, whisperer lid, K&N filter, !MAF screen, raised air box, free ram air, im getting a lot of air in there, i was just thinking to get more fuel in there to even it out, but i guess i could be wrong. oh well just wondering...

Before you do things like this, you need to know the duty cycle of your injectors. eg, autotap, etc. You can still run lean and have plenty of injector left. If that is the case, you can use a MAFT to richen it up if needed. IIRC, Magnus is running stock injectors and running 13's NA. So I doubt you "need" them. Some people have been know to use them as a bandaid to programming, like if you went to a bigger MAF setup or something.

I would really doubt your running lean. Stock injectors should be able to compensate for the added air flow. Keep your injectors you should be fine for now.
